In addition, the conveying path converter mechanism 22 stops the operation of the solenoid so that the conveying path returns to the main conveying path 8a side, while the conveying path is in the main conveying path 8a side while the operation of the solenoid is stopped. It is configured to stay on.

The operation display section 4 (see the operation display section in FIG. 1) is a button required for the operator to operate, such as an operation for selecting a processing mode or changing a determination criterion (threshold value between the upper and lower limits) used for authenticity determination and the like. In addition to the above, it has an indicator for displaying the processing result and the like.

The storage section 24 stores data, programs, and counting results of bills required for identification of paper money and authenticity of bills. The storage section 24 is composed of predetermined recording media such as ROM and RAM. The gold type determination table 24a stored in the storage unit 24 is a table in which the gold type determination data for at least one currency is registered. Data (hereinafter referred to as "gold seed identification data") is registered. The processing mode 24b memorized in the storage unit 24 is a mode indicating the operation mode of the banknote identification counter, and in addition to the " gold seed identification mode " We install "heterogeneous currency identification mode" about. In the present invention, the "heterogeneous currency identification mode" refers to a currency other than the currency in which the denomination judgment table 24a is prepared, that is, a currency that does not have the denomination judgment table 24a. This mode is a mode for performing the processing of, and this mode is used when, for example, the banknote inspection and authenticity determination are performed on the banknotes of the countries of the Euro member countries.

The determination criterion information 24c stored in the storage unit 24 is information indicating a determination criterion when making a judgment or authenticity determination of a different kind in the heterogeneous currency identification mode. In this example, the difference between the detection data of the first sheet and the detection data of each banknote after the second sheet is compared with the allowable range, and if it exceeds the allowable range, it is determined that it is a dual class, and information indicating the allowable range ( Threshold values of the upper limit and the lower limit) are stored as the decision criterion information 24c.

The paper type identification means 25 is a means for identifying a banknote for the currency in which the paper type determination table 24a is prepared, and in the paper type identification mode, the detection data of the paper money detection sensor 31 and the gold type determination table ( Based on the data of 24a), the paper type identification, authenticity determination, and gold type counting processing of the banknote are performed.

The processing mode converting means 26 is a means for converting each of the above-described modes, and in addition to the function of converting the processing mode by an operator's operation, the function of automatically converting the money identification mode (initial mode) to the heterogeneous currency identification mode. Equipped with.

The heterogeneous currency identification means 27 is a means for performing heterogeneous species inspection and authenticity determination in the heterogeneous currency identification mode, and is based on the detection data of the first bill obtained by the line sensor (or the line sensor and the magnetic sensor). By comparing the difference of detection data with the first sheet with respect to the second and subsequent bills, the identification of whether or not the bill is different from the first bill with respect to (or the identification thereof) based on the comparison result. And authenticity determination of banknotes)

The decision criterion changing means 28 is a means for changing the setting information of the allowable range (decision criterion information 24c) used for the above comparison to the allowable range designated by the operator. This determination criterion changing means 28 is provided so that adjustment of the setting of the determination criterion information 24c used for the different types of paper money inspection and the authenticity determination can be adjusted so as to meet the banknote situation of each country.

The control means which comprises the control part 20 controls each mechanism and each part connected to this by a predetermined program, For example, a microprocessor etc. can be used.

In addition, each said means 25-28 is implement | achieved by the computer program controlled by the control part 20 in this embodiment, and is memorize | stored in the predetermined | prescribed storage medium. Then, it runs as a memory resident program or an overlay program at the time of execution. In addition, each means 25-28 is classified as a function by attaching a means name for the convenience of description, and does not limit a software structure. In addition, although the identification part is comprised from the banknote detection sensor 31, the memory | storage part 24, and each means 25-28, the aspect which inserted the control part 20 in the identification part is also included in this invention.

In the configuration as described above, the operation in the case of processing the flow path currency will be described with reference to FIG.

Since the banknote identification counter which concerns on this invention originally aimed at a euro currency, it does not need designation for processing a euro currency. That is, the default is the euro currency. In addition, as the processing mode, the gold species identification mode is set as the initial mode.

When the operator mounts the mixed denominations of the euro currency on the hopper unit 3 and presses the start button of the operation display unit 4, the feeding mechanism unit 7 is operated to feed out in order from the lowest bill, and part of the identification unit In the line sensor LS constituting the same, the long bill size / short length bill of the bill is measured, and an image of the bill is scanned, and if the same thing exists with reference to the bell type determination table 24a, it is specified as the bell type. . Then, the number of bills judged to be normal by the paper type identification means 25 is counted for each gold type at the time when the paper money counting sensor passes the number counting sensor PS5, and is aligned and accumulated in the stacker unit 5. On the other hand, when it is determined that it is not normal, the conveyance destination of a banknote is converted to the branch conveyance path 8b side by the drive of the conveyance path converter mechanism 22, and the banknote is conveyed to the reject part 6.

Next, the operation | movement in the case of processing the koruna which is a Czech banknote, for example, in which the denomination judgment table is not prepared is demonstrated.

The operator operates the operation display unit 4 to select the heterogeneous call identification mode.

This heterogeneous currency identification mode is based on the characteristics of the banknotes encountered first (in this example, the dimensions of the banknotes, the presence of magnetism, the presence or absence of a response to the infrared region light, and the color), and the detection data of the characteristics. Is stored in memory.

The heterogeneous currency identification means 27 compares the detection data of the banknotes encountered thereafter with the reference data stored in the memory, and guides the banknotes judged to be different to the reject unit 6.

It is judged that it is different from the first kind, and the kind of gold is a fake bill.

In addition, even if the direction of banknotes of the same paper type overlaps with the hopper part 3 differently, it is not judged as a two-kind paper by the following correspondence.

As shown to FIG. 5A-FIG. 5D, the banknote P has four types of directions. The memory stored in the memory is, for example, the positional information of the shape Pa in the drawing, and the calculation means allows the contrast in four types of directions of the bill P to be performed. Will not. Specifically, the heterogeneous currency identification means 27 compares the reference data stored in the memory (for example, image data in a two-dimensional array by RGB and infrared light) with the second and subsequent detection data. For example, the order of either two-dimensional array data is converted and contrasted in four types of directions of the banknote P is performed.

Next, a specific example will be described and described in accordance with the flow of the flowchart of FIG. 6 with respect to the processing of the heterogeneous type inspection and the authenticity determination in the heterogeneous currency identification mode.

In the heterogeneous currency identification mode, the banknotes of the same kind of paper are tested, and the authenticity of each paper money is examined (inspection of whether or not bills of different kinds of paper are not mixed in the paper money). Here, as shown in FIG. 7, the banknote P (N1) and the 2nd banknote P (N2) are the same on the basis of the first banknote P (N1) encountered first. The case where the third banknote P (N3) is different is taken as an example.

First, the operator operates the operation display unit 4 to select the heterogeneous currency identification mode, changes the processing mode from the denomination identification mode to the heterogeneous currency identification mode, and mounts a plurality of banknotes in the hopper unit 3. When the start button is pressed (step S1), the feeding mechanism 7 is operated to feed out in order from the lowest bill, and when the first bill P (N1) passes through the line sensor LS (Fig. 3). Reference is made to the image of banknote P (N1) shown in FIG. 6 (step S2), and image data of banknote P (N1) is taken. In this example, the image data collected by the line sensor LS is one of data by infrared light (light amount in the infrared region penetrating the paper), and one of R (red light), G (green light), and B (blue light). Color data by the above-mentioned light (preferably light quantity of each reflection light from banknote with respect to each irradiation light of RGB tricolor). The heterogeneous currency identification means 27 extracts the edge of a banknote based on the image data of the banknote, and calculates the dimension of the banknote with the long length (size in the long direction). In addition, you may make it the form which computes not only the dimension of a banknote in length in this case, but also the dimension of shorter length (size of shorter length direction). In addition, instead of obtaining from the image data of the line sensor LS, the dimension of short banknote length may be calculated | required based on the detection signal of the said identification control sensor VP1. That is, the banknote length P _L (the dimension in the Y direction in the conveying direction) is detected by the detection signal of the banknote by the identification control sensor VP1 shown in FIG. 3, and the two identification control sensors VP1 are detected. The meandering degree of the banknote may be detected from the passing timing of the banknote, and a dimension having a short length of the banknote may be obtained based on the detection information thereof (step S3).

When the first banknote P (N1) passes through the magnetic sensor MG shown in Fig. 3, the magnetism of the banknote is detected by the magnetic sensor MG, and when it is detected, it is detected by the magnetic sensor MG. The signal is output. The heterogeneous currency identification means 27 detects the presence or absence of magnetism of the first banknote P (N1) by the presence or absence of the detection signal of the magnetic sensor MG (step S4).

And the detection information of the 1st banknote P (N1) obtained by the process of said step S2-S4 is memorize | stored in memory as reference information SD (1) used for the following steps. Specifically, the heterogeneous currency identification means 27 includes data indicating the size of the banknote including the dimension information of the first banknote P (N1) (in this example, at least the length of which is obtained in step S3). ), Color information (image data of banknotes by one or more of red light, green light, and blue light), image information of the infrared region (image data of banknotes by infrared light), and magnetic information (indicative of the presence or absence of the magnetism of the banknote) Data) is stored as the reference information SD (step S5). And the counter N which shows how many banknotes is the next banknote is made into 2, and the process with respect to banknotes after 2nd sheet is performed (step S6) below.

In addition, in this embodiment, although the length of a banknote is long as an element of the determination criterion information 24c, the dimension with a short length is also detected as mentioned above, and length is determined as an element of the determination criterion information 24c. Both long and short lengths may be used, or short lengths may be used instead of long lengths.

Subsequently, the heterogeneous currency identification means 27 receives the first sheet obtained by the processor of the above steps S2 to S4 when the second banknote P (N2) passes through the line sensor LS and the magnetic sensor MG. Similarly to the detection information of the banknote P (N1), detection information of the second banknote P (N2) is obtained (step S7).

Then, the difference between the reference information SD of step S5 and the detection information of the second bill P (N2) is calculated for each reference element (step S8), and the difference and determination standard information for each reference element are calculated. 24c (information indicating the permissible range) is compared (step S9).

Here, the specific example is shown and demonstrated about the determination criterion information 24c used at said step S9.

The determination criterion information (the allowable range of the difference with respect to the first sheet) of the long dimension is, for example, ± 1 to 15 mm, and when the shorter dimension is added as an element of the determination criterion information, the determination criterion information Is, for example, ± 1 to 15 mm.

The determination criterion information for determining that there is infrared light response is that the A / D conversion value of the infrared detection signal output from one channel of the line sensor is 0 to 255, and the image data of the banknote by infrared light (data of two-dimensional array). The threshold value which judges comprehensively that there is infrared light reaction is 1-15. However, in the case where the signal indicating the presence or absence of infrared light detection is output from the line sensor side, the determination reference information is not necessary.

As for the criterion for determining the presence or absence of magnetism, the threshold value for determining the presence of magnetism is that the threshold value of the magnetic detection signal in one magnetic detection element is 0 to 255, and the threshold value for comprehensively determining the presence of infrared light reaction. Is 1 to 15. However, in the case where the signal indicating the presence or absence of the detection is set as an output on the magnetic sensor side, the determination reference information is not necessary.

From the image data (data of a two-dimensional array) of the banknote by the light of R, G, and B output from a line sensor, the threshold value which determines comprehensively the same banknote as the 1st sheet is 1-15. In addition, the area | region of a banknote is divided | segmented, and the average value etc. are calculated | required and determined with respect to each division block. In that case, determination reference information for each divided block is prepared, but the threshold value as the determination reference information is a threshold value of an upper limit and a lower limit similarly to the above-mentioned threshold values.

As described above, the determination criterion information can be changed by the determination criterion changing means 28 in accordance with each banknote situation of each country.

In the heterogeneous currency identification means 27, when comparing the difference between the reference elements and the determination reference information 24c in the step S9, the plurality of determination reference information as described above is used to compare the determination reference information. Then, on the basis of the comparison result, the foreclosure type inspection and authenticity determination of the N-th bill are performed. In the heterogeneous currency identification means 27, at least the length of the banknote in the long direction is regarded as an essential element of the criterion, and each other element (in this example, the color information, the image information of the infrared region, and the magnetic field). Presence or absence), any one or more elements are added, and the different species testing and authenticity determination are performed. In addition, the matching process based on image information is a well-known technique by this applicant etc., The description is abbreviate | omitted.

For example, the different types of currency identification means 27 include reference information SD (1) of the first banknote P (N1) and the second banknote P (N2). When comparing the difference with the detected information with the allowable range, if the difference in the dimension in the longest direction is at least the allowable range, it is determined as "Double type", and the difference in the dimension exceeds the allowable range, If the difference between any one of the elements of color, infrared, and self exceeds the allowable range, the combination is determined in advance. Based on the combination of the respective elements, the " different species " and " authentication " are determined (step S10). In addition, it is preferable that the said combination used for the determination process of step S10 makes it possible to change a combination by the determination criterion changing means 28 according to the banknote conditions of each country.

In the determination in step S10, it is determined whether the N-th bill is a dupe or fake (step S11), and if neither of the dupe or duke is in other words, that is, the N-th bill is the same as the first bill. In the case of a gold type and determined to be "real", when the N-th banknote passes through the counting sensor PS5, the count value of the number of the normal banknotes is updated, and then the stacking unit 5 is aligned and stacked. do. In parallel with this, the heterogeneous currency identification means 27 detects whether the hopper part 3 has a banknote by the hopper part sensor PS1 (step S12), and, if there is a banknote, the counter ( After adding 1 to N) (step S13), the process proceeds to step S7 and the processing of the next banknote is continued.

On the other hand, in the above-mentioned step S11, the banknote (the third banknote P (N3) in the example of FIG. 6) that is determined to be a banknote or a fake is transferred to a branch conveyance path by driving of the conveying path converter mechanism 22. It is converted to the (8b) side, conveyed to the reject part 6 (step S14), and it moves to step S12 and the process of the next banknote is continued.

In addition, in the above-described operation example, when it is determined that the banknote is fake or fake in step S11, the banknote is returned to the reject unit 6 to continue the next process. It is good also as a form which stops the drawing | feeding-out conveying mechanism 21 at the time which it has become.

Next, an embodiment in which the processing mode of the banknote is automatically converted into the heterogeneous currency identification mode and the processing such as the different paper type inspection is executed will be described.

In the above-described embodiment, the processing of the heterogeneous currency identification mode has been described as an example in which the operator starts pressing the start button after changing the denomination identification mode to the heterogeneous currency identification mode, but the banknote identification counter according to the present embodiment is described. Has a function of automatically converting the money type identification mode (initial mode) to the heterogeneous currency identification mode.

Hereinafter, the function will be described with reference to FIG. 8.

When the operator mounts the hopper unit and presses the start button of the operation display unit, the banknote identification counter first operates in the paper type identification mode. In the paper type identification means, a process of identifying the gold type of the currency is performed with reference to the gold type determination table for the first bill. At that time, when it is determined that the paper type identification data of the first bill P (N1) is not registered in the paper type determination table 24a, the processing mode of the paper money is changed from the paper type identification mode to the heterogeneous currency by the processing mode converting means. While switching to the identification mode, the heterogeneous call identification means is activated.

The heterogeneous call identification means activated by the processing mode converting means executes the processing in the heterogeneous call identification mode, starting from the processing in step S5 of FIG. Since the process after step S6 is the same, description thereof is omitted.

In addition, the detection data output from the various sensors in the denomination identification mode includes data collected by the heterogeneous currency identification means, and the common data used by the denomination identification means and the heterogeneous currency identification means is the same storage destination [ Non-routing address]. Therefore, the heterogeneous currency identification means can use the data collected by the money type identification means as it is.

As described above, in the heterogeneous currency identification mode, since the same sensor as the sensor performing the denomination is used, the same device is used to identify the denomination of the Euro banknote and the banknotes of other countries without adding a new sensor. It is possible to carry out a poultry species inspection and authenticity determination.

In each of the embodiments described above, the euro currency is described as an example of the common currency of each country, but the banknote identification counter according to the present invention can be applied to common currencies other than the euro currency. Moreover, although the banknote identification counter which has the "count mode" which performs only a count is taken as an example, this invention can be applied also to the banknote identification counter which does not have a "count mode." In the heterogeneous currency identification mode, as a criterion for determining the types of money and authenticity, the size of the bill is an essential element, and as other elements, (a) color information, (b) image information of the infrared region, and (c) self Although the case which has all the elements (a)-(c) of the presence or absence was demonstrated as an example, one other element (a)-(c) may be sufficient. Moreover, although the banknote identification counter which made the banknote the short direction of a banknote as the conveyance direction was demonstrated as an example, this invention is applicable also to the banknote identification counter of the form which makes the banknote the longitudinal direction of the banknote long.

Although the banknote identification counter which concerns on this invention targets banknotes, this invention is applicable also to the identification counter which targeted paper sheets (gold bonds, such as securities and gift certificates) other than a banknote. Moreover, although this invention is suitably applied to the desk type banknote identification counter as shown in the figure, it is not limited to a desk type thing, It is applicable also to the banknote identification counter of the general size which is widely spread.
